My Problem

My iPhone 4S wouldn't charge. I tried using different outlets, different cables, different computers, none worked. I cleaned out the lint and that seemed to work, but only for a few hours. I learned that in the car my partner had dribbled some water on it while it was plugged in. I couldn't see any damage to the dock connector or any signs of water damage inside, so I bought and installed a new battery (also with help from iFixit). The phone still wouldn't charge. I figured I would try replacing the dock connector since it was cheap and looked easy.

My Fix

I bought a used (A-stock) dock connector rather than new to save $5, which was 25% less. I'm a big fan of recycling and repurposing. Plus, the mining, manufacturing, and shipment of electronics such as these are one of the biggest sources of negative environmental impacts, so keeping one more new item on the shelf until it's actually needed was important to me. I also used to work in a business that sells used auto parts. I've learned how good of a job a quality-controlled used part can do. I followed the guide forwards and backwards and ended up with a working phone again! Easy.

My Advice

The steps to disconnect the battery cable are confusing. The cable plugs down onto 4 pins and the piece that pulls up has an overhanging lip around the outside that makes it easy to pry up with little force. There is a small contact plate (black with a copper nub) that is visible, but half of it is under the cable plug around the top screw. It is only held in place by that screw and friction between the cable plug and the components beneath it. Don't worry when this piece comes loose because it is not attached to anything, just keep track of it.

Be very careful with the ribbon for the home button. The ribbon slides horizontally in and out of the connector and the locking tab that holds it down is hinged (it flips up and down like a roller coaster bar). If you've ever taken apart a laptop you'll be familiar with these. When you reinstall it, don't twist it side to side, but rather tilt the back of it up (vertically) until the tip of the ribbon rests on the entrance to the connector then tilt it down so it slides in. This is much easier to do with two hands, using small tipped tools. I don't think using tweezers is necessary.

Read the full description, including alerts, on each step before starting the work. Also check the comments for problems that other people have run into.

Work on a brightly lit surface and use a hands free magnifying glass if you have bad vision.

I recommend wearing latex gloves to keep the oils from your hands off the electronics. I also used 91% Isopropyl Alcohol and cotton swabs to clean all the metal contacts.

Keep track of those screws! I used a small ceramic tray and taped them down with scotch tape. I kept track of where each screw belonged with notes on a sticky note.

Try not to work in a room with carpet or a dirty floor. If you do drop a screw, here are a couple tips: 1) Hard floor: turn off all the lights and lay a flashlight on the floor; the angle of the light will cause even small items to cast longer shadows and be easier to see, 2) Carpet: put a nylon leg hose or other fine filter over the attachment wand on your vacuum and use it to sweep along the floor; this saves you the hassle of searching the dusty vacuum compartment, 3) Any Floor: a strong magnet.

My Problem

I was trying to take the back off because it was cracked. I did not have the proper tools and I just made it worse.

My Fix

This was so easy to repair after I received the tools and parts from IFIXIT!

My Advice

Don't brake your son's phone!

My Problem

Was having intermittent charge and sync issues with My 4S Doc Connector.

My Fix

Repair was easy with the pictorial repair guide from the website. 1 hour or so is all it took. This was my first repair for this phone.

My Advice

Lay out and tape a big piece of white paper (24" x 24" )to a flat work surface. The tape is so you don't have to worry about catching the paper and shifting all the little screws around by accident. As you take the parts out write on the paper size Ie 1.2mm Phillips etc. and description of part. There is plenty of room to keep the parts separated to help ease any confusion of similar looking screws.

My Problem

After having fixed the battery and speaker issue, ( https://www.ifixit.com/Story/12618/iphon... ), I had noticed that even when plugged in, every now and then, the iphone 4S would just suddenly start discharging, as if it were not plugged in. Also, when I replaced the speaker in my previous repair, I did notice that there was some warpage of the old speaker assembly, as if that part of the speaker assembly got excessively hot. From those two things, I assumed there was a possible short in the dock connector assembly.

My Fix

The repair went quite smoothly. That iScrews iPhone Screw tray comes in handy for the repair process, in making sure I know where every screw I removed went.

I delayed writing this success story, to verify that the intermittent discharging while plugged in problem was no longer present, and the problem is indeed fixed. Darned good thing I did buy the dock connector assembly even when I thought I didn't previously need it.

My Advice

Replacing that rubber spacer can be rather tricky. Just take your time, and get a good light source.

My Problem

Docking connector had a chunk missing and bent pins. Also my phone would die in about two hours of non use or less than an hour of use, so I had to carry my charging cable and an external charger everywhere.

My Fix

Fantastic! My phone can now sync to a computer and charge with any cable. I had to have a specific cable that used the pins I had left to charge it. My phone can also go all day without being plugged in with moderate use.

My Advice

Step 4 of the battery/docking connector removal and replacement was almost disasterous. The screwdriver from the iFixit toolkit didn't have the correct size and started stripping one. Luckily the screwdriver from the Liberator Kit fit perfectly.

Also Step 16 of the docking cable replacement was kinda vague, and I kinda stumbled on the retaining flap by accident. It was hard to tell what exactly I was opening from your pictures. I was actually prying on the metal for the docking port for a bit before I stopped afraid I was going to break it. I was just looking at it with the spurger when it hooked the flap accidentally. Then I picked up along like nothing happened, lol.

But putting it all together was the easiest part and after a soft reset my phone picked up the surrounding towers and had the correct time and date. Total success!

My Problem

After 3 years, my iphone 4s dock connector finally got too damaged and the phone would no longer charge or connect to itunes for backup. Of course it became very dead.

My Fix

The repair went well by following your almost perfect online instructions - with one exception described below. My iPhone works perfectly again and even though the phone was COMPLETELY dead, all my information was still there once it charged (thank you flash memory!).

My Advice

This is the reason I'm telling my story. The instructions are very good, except the part about the microphone! Step 18 details removing the mic from the phone case. Step 21 has a secondary sub section about the mic case and reassembly, but it's not a "step" so I somehow missed it, and it doesn't have the necessary detail anyway. Therefore I didn't realize the rubber "case" holding the microphone was a separate piece until I had already put the new dock assembly in the phone. It would be SO much easier to put that rubber case on the mic BEFORE installing the dock in the phone! IMHO this should be a separate and last step, because it is important to a successful project and isn't (at least to me) obvious. You DEFINITELY want to install that rubber case onto the mic chip before you put the new dock in the phone because the mic chip has a glue strip to hold it in place within the rubber case, and it's rather difficult to get the mic aligned correctly in it's case with the glue strip sticking as you slide it in, all while working within the very tight confines of the phone case. I did it the hard way, because I didn't want to remove the just installed new dock assembly, thereby weakening the glue strips that hold it in place. My mic seems a little muffled compared to before, but I'm not sure. If there is a difference in quality, this is almost certainly the reason, as I couldn't tell if the mic "hole" on the chip was lined up with the hole in the mic case from the angle I had to work at with the dock in the phone case. For ADD people like me who don't necessarily read every word and like pictures, please add a separate step for the mic case installation at the end of your otherwise great instructions.

My Problem

Phone won't turn off, loss of sounds

My Fix

Took about 2 hours total, fixed the problem phone works normal

My Advice

Line up all the parts removed for easier reassemble

My Problem

Customer's iPhone wasn't turning on or charging, had to rush the order out based on the problem she described before receiving the device because I'm in New Zealand. Shipping was pretty quick nonetheless, received it the next week.

My Fix

Received the phone and before I started taking it apart I noticed a few things. Firstly, one of the external screws were missing and the other was a Phillips, meaning the device had been opened before. Secondly, a lot of screws internally were missing, and a few components were cosmetically damaged. Horrible job by either someone who previously owned the device or worse, a dodgy repair shop (which are plentiful here). The dock connector was also black, this was a white iPhone, so I'm guessing that component was replaced before. They either didn't bother checking iFixit or decided to do it without the proper tools.

I decided to go ahead with the repair anyways. Once I had the new connector in I just tacked on the battery and plugged it in. The device instantly powered on and the charging indicator was displayed. I then followed the guide in reverse to put the phone back together and the customer was very pleased with the professional and timely job.

My Advice

If you don't have enough business to maintain a stock of common parts (screws, connectors) for your customers' devices, be patient. Advise them that you would prefer to order the parts once you've seen inside the device. I lucked out, but I also had to tell my customer if she wanted her iPhone to last as long as possible I would need the device back once I ordered in some replacement screws. If you're a wholesale member on iFixit you're already going to be cheaper and more professional than the guys around your area, and most people don't seem to mind waiting for that.

My Problem

phone wasn't charging or connecting to computer

My Fix

replaced the dock was relatively easy, however, it was a bit delicate because some of the components use an adhesive that makes removal a delicate operation

My Advice

be careful and proceed with caution, don't rush, and you will be rewarded with fixed device

My Problem

After many years of use, the dock connector on my iPhone 4s had become corroded and was causing problems with the phone such as poor charging and not being able to shut the phone down (it would just restart itself when you tried to power it off).

My Fix

The repair went incredibly well. I've built and repaired computers for years but had never cracked a cell phone open until today.

First off, I absolutely love the Pro Tech Toolkit. When I first decided to do this fix myself, I debated on just buying the few tools I'd need for this specific repair or to get the Pro Tech Toolkit in anticipation of doing many more repairs in the future. I'm very glad I chose to get the Pro Tech Toolkit! It is compact but packed with just about everything I'll need in the future and the high quality of the Tool Roll and all the tools inside is obvious when you are holding and using them.

I received the Magnetic Project Mat as a Christmas present this year and it was integral to making my first repair successful by easily organizing and keeping the tiny screws and parts right where I put them. Being able to write right on the mat with the dry erase pen made keeping notes about specific parts a breeze.

My Advice

1. Before you do anything, read through the walk-through for your specific repair. There are lots of little pieces of info that make the repair easier.

2. Set up your work area and pull out the tools you know you'll be using so they are at the ready.

3. Lighting - The screws and some of the parts you will be dealing with are TINY so having good lighting is paramount. The lighting in my office is okay, but I hooked up a flexible USB reading light to an external battery and it worked awesome! It was easy to move around and position where I needed it which really helped.

4. Time - Make sure to give yourself plenty of time to make the full repair with as little distractions as possible. This really helped me get through the repair faster.

A few notes about the walk-through.

STEP 3 - The suction cup in the Pro Tech Toolkit is very handy here.

STEP 6 - When you pry up the battery, the adhesive makes a really horrible sound and tries to trick you into thinking you're doing something wrong. It lies, just go slowly and you'll be fine.

STEP 9 - When you are re-assembling your 4S, it is a little tricky to get the dock cable socket to fit correctly when you are putting it back in. My extra light helped a lot here and I used the tweezers to gently position the cable so the socket was oriented correctly before pushing it down with my finger. It should make a soft little snap and it won't wiggle around at all when it's seated correctly.

STEP 12 & 13 - When unscrewing the left side screw for the speaker enclosure, the small black spacer from STEP 13 came up with the screw. Be careful when you are removing this screw so the spacer doesn't get lost.

STEP 14 - During re-assembly, don't forget to clean the metal-to-metal points as directed in the walk-through. You can get a small bottle 99% Isopropyl Alcohol at VONS or Safeway. It is recommended to use 99% Isopropyl Alcohol for sensitive electronics because evaporates very fast so the parts are completely dry before you finish the re-assembly. I used a Q-Tip to apply it and gently scrub the parts.

STEP 15 - I saved this little piece of tape but didn't end up needing it because my replacement part had a new piece right where it needed to be.

STEP 18 - During reassembly, getting the little rubber tube back inside the plastic part was a little tricky but using the tweezers from the Pro Tech Toolkit I was able to get it back in after a moment of fiddling with it.

STEP 20 - This little piece of rubber is VERY tiny. One of the sides is shinier than the other and that is the side with the adhesive on it so be sure to put that side down during re-assembly.

STEP 21 - As the TIP in the walk-through says, you will need to transfer the little rubber casing from your old part to the new part. Lay both parts side by side and examine where you're taking the rubber casing from so you'll know where it goes on the new part. As the walk-through mentions, you can use the fine tipped spudger to loosen the rubber casing from the old part before you transfer it to the new one.

  • IMPORTANT NEW PART INFO *****

Before you transfer the rubber casing to the new part, look carefully at the microphone nodule on the new part and you will see a clear protective film that sticks off the side of the nodule. The protective film can be easily removed with tweezers before you transfer the rubber casing.

There will be another piece of protective film on the section of the part that the microphone is connected to. Examine the rest of the new part and you will find several other pieces of protective film that you will need to remove as the re-assembly progresses. Some of the protective film covers adhesive that will keep the new part in the proper place when re-assembly is complete.

I hope these notes help you with your repair!
